OnePlus 15 After 12 Months: Is the Best Gaming Phone Worth Buying Now?

The OnePlus 15 packs a 7,300mAh battery, and 91mobiles measured 17.1 hours of PCMark runtime on it. That is six hours more than the OnePlus 13 managed. A year after launch, it is still one of the longest-lasting flagships you can buy.

However, the OnePlus 15 is not a complete flagship. Its camera trails the best from Oppo, Vivo and Apple, and it runs warm under load. So the real question is whether battery and speed matter more to you than photos.

We have not used this phone ourselves. Therefore, everything below comes from published reviews, lab numbers and a live price listing, and we name the source each time. Where reviewers disagree, we say so.

OnePlus launched this phone in November 2025. Since then, rivals have arrived with better cameras. Yet few have matched its battery.

That makes the OnePlus 15 a specialist. In short, it does two things better than almost anyone, and one thing worse than several rivals. Knowing which group you fall into settles the question.

A newer model also exists. The OnePlus 16 launched in China in October, as we covered in our OnePlus 16 vs OnePlus 15 comparison. Most buyers still cannot get it, so the OnePlus 15 is the phone on the shelf.

The Short Version

• Battery is the headline. Lab tests and long-term reviewers agree on a day and a half, and often more.
• Speed is excellent. The Snapdragon 8 Elite Gen 5 beat the iPhone 17 on AnTuTu and Geekbench in 91mobiles’ tests.
• The camera is the weak spot. Reviewers call it good for social media, not the best in its class.
• The 165Hz screen is mostly a gaming feature. Daily use runs at lower refresh rates.
• Buy it if you game a lot, hate charging, and take casual photos.
• Skip it if photography is the main reason you upgrade.

OnePlus 15 Battery Life: The Reason to Buy It

This is the strongest part of the phone. First, the 7,300mAh silicon-based cell lasts far longer than the 6,000mAh battery in the OnePlus 13.

In 91mobiles’ PCMark test, it ran 17.1 hours from 100% to 20%. The Oppo Find X9 Pro lasted 16.0 hours despite a 7,500mAh cell, and the OnePlus 13 lasted 11.4 hours.

Real use points the same way. The same reviewer finished heavy days with 40-50% left, which means about a day and a half. In another long-term review, Outlook Business reported the battery reaching a third day in lighter use, with about nine hours of screen-on time.

Charging is fast too. Specifically, the phone supports 120W wired charging. BusinessToday found a full charge took roughly 35 minutes, while Outlook Business said about 40. The gap is small, so call it 35 to 40 minutes.

One catch applies to wireless charging. The phone supports 50W wireless charging, but it has no built-in magnets, so you need a magnetic case to use accessories properly.

Performance and Gaming: Fast, but Warm

The Snapdragon 8 Elite Gen 5 is Qualcomm’s current top chip. In 91mobiles’ tests, the OnePlus 15 scored 3,615,565 on AnTuTu. The iPhone 17 scored 2,250,422.

BusinessToday measured about 3.7 million on AnTuTu, so the two labs agree. BusinessToday also says real-world differences from other flagships are subtle, so benchmarks exaggerate the gap.

Gaming is where the phone shines. For example, BusinessToday saw BGMI hold close to 120fps in heavy fights. After a two-hour gaming session, the battery was still at 65%.

Heat is the trade-off. 91mobiles said the phone ran warmer than rivals and throttled more in its Burnout test. Outlook Business, by contrast, found it only needed a short breather during heavy use. So expect warmth, not a problem, in normal play.

Here is how the numbers compare in 91mobiles’ lab:

The table tells a clear story. Overall, the OnePlus 15 wins on raw speed and endurance. It loses on sustained performance to the iPhone 17, which held its pace far better.

The OnePlus 15 Camera: Good Enough, Not Great

This is where reviewers push back. Notably, OnePlus ended its Hasselblad partnership and built its own DetailMax Engine. Early results were mixed.

The hardware is three 50MP cameras: a main, an ultrawide and a 3.5x telephoto. According to 91mobiles, daylight photos are saturated and reliable. Portraits at 3.5x impressed, and the phone recorded detail slightly better than the iPhone 17 there.

Low light is weaker. 91mobiles found the iPhone 17 captured brighter, more detailed night scenes. BusinessToday agreed that low light was noticeably weaker than on the OnePlus 13, with more noise.

Outlook Business was blunter. Its reviewer said the camera trails Oppo and Vivo, and called the ultrawide a disappointment. They also said the 7x option is a digital crop with flat results.

Video is a bright spot. Indeed, 91mobiles says the OnePlus 15 can shoot 4K at 120fps with Dolby Vision on its main camera. That is rare.

The fair summary is this. If you share photos on social media, the camera is fine. If you print them, crop them, or shoot at night, look elsewhere.

OnePlus 15 Display, Design and Software

The 6.78-inch screen is a 1.5K LTPO panel with a 165Hz maximum. Reviewers agree it looks sharp, and 91mobiles measured up to 1,800 nits in high brightness mode.

Do not buy it for the 165Hz, though. According to BusinessToday, only the home screen, menus and a few games reach that rate. Outlook Business called it mostly unusable in daily life.

Build quality is strong. In fact, the phone carries IP66, IP68, IP69 and IP69K ratings, so it resists dust and hot water jets. The design is flat and plain, which some reviewers liked and others found dull.

Software is OxygenOS 16 on Android 16. OnePlus promises four OS updates and six years of security patches, according to BusinessToday. BusinessToday calls that respectable but behind Samsung and Google. We compared the promises in our OnePlus 15 vs Pixel 11 software comparison.

OnePlus 15 Verdict: Who Should Buy, Wait or Skip

Scores are strong but not unanimous. For instance, 91mobiles rated the phone 8.4 out of 10, praising its performance, battery and polished software. It also called the camera not the best in its class.

Outlook Business, after more than a month, said the camera keeps it from being an automatic daily driver. Its reviewer wrote that they would have switched to it without a second thought if the cameras were twenty percent better.

Both reviewers point photography buyers to the Oppo Find X9 and Vivo X300, and Outlook Business adds the iPhone 17. For an Apple option, see our iPhone 17 Pro Max verdict.

Buy the OnePlus 15 if:

• You play demanding games and want the longest battery you can get.
• Charging often annoys you, and a full battery in under 40 minutes appeals.
• Social-media-grade photos are good enough for you.

Wait if:

• You want a newer chip and bigger battery. The OnePlus 16 has launched in China, but a global launch is not confirmed.
• You want longer software support than six years of security patches.

Skip it if:

• Camera quality is your top priority. Oppo, Vivo and Apple shoot better in low light.
• You want a phone that stays cool and fast under sustained load. The iPhone 17 throttled far less in 91mobiles’ test.

Our call: it is a strong phone with one clear weakness. For the right buyer, nothing else matches its battery.

India Price, Retailers and Offers

This section covers India only. Prices were checked on 14 November 2026.

The OnePlus 15 launched in India at Rs 72,999 for 12GB RAM and 256GB storage. The 16GB and 512GB version launched at Rs 79,999, according to BusinessToday.

Today the price is higher. Smartprix lists the 12GB model at Rs 85,999 on Amazon, with the price last changed on 12 November 2026. That is Rs 13,000 above the launch price.

Smartprix also lists a 16GB and 512GB model at Rs 79,998. That sits below the base price, so we could not reconcile it. Check the Amazon page before you pay.

At Rs 85,999, the value case is weaker than it was at launch. After all, the phone is a year old and a successor exists abroad. We covered the tipped price of that successor in our OnePlus 16 price report, and it is not confirmed.

Our India advice: buy at or near Rs 72,999 if you can find a deal. At Rs 85,999, only buy it if the battery and gaming performance are worth that premium to you. Bank offers change often, so we do not quote any here.
